Hi Sherileigh
I really admire any woman who pumps and bottle feeds her baby! It is not easy! WELL DONE you!!! It sounds like you are one determined, dedicated mamma!!!! And the breastpump issues sound really difficult - when you depend as much as you do on the pump, then it's VITAL to get the right parts!!! Well done you!!!!
There are some great tips on getting more milk when pumping here: https://www.llli.org/NB/NBJulAug96p118.html and I hope between that and the domeridone you are able to continue until you and your lovely LO feel ready to wean.
